While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 63: Mushrooms of Madness

Chapter 63: Mushrooms of Madness

After a shocking wake-up (for me, at least), we both finished breakfast.

Our Saturday’s just getting started.

On the bed, its upper half raised by the reclining function, now more like an oversized chair…

Still bound at all four limbs, I sat limply, legs sprawled, leaning against the wide backrest.

—And then, there’s Yuu.

“Ren-chan!♥”

Stroke, stroke. Stroke, stroke.

“Ren-chan!♥ Nfufufu…♥”

Perched on the bed’s edge, she called my name with a tender smile.

It’s almost a look of pure affection, but her hands were busy stroking my chest.

“Such a nice chest…♥ Honestly, Ren-chan, you’ve gotten so ripped!♥”

“…”

Stroke, stroke. Stroke, stroke.

She’s feeling my pecs, occasionally sliding down to my abs, then back up to savor my chest muscles.

“You used to be way skinnier!♥ Always cool, but now you’re even cooler!♥ I love that about you!♥♥♥”

“…”

Yuu’s over the moon. Beaming with joy, she’s relishing my skin and muscles through my shirt. Her grin’s so loose it’s almost sloppy, making me a bit uneasy.

What’s so fun about touching a guy’s body?

Curious, I asked.

“My manly pecs—is touching them that fun?”

“Absolutely!♥”

“…I see.”

I don’t get it. No matter how you slice it, a woman’s body feels more thrilling to touch.

My chest? Just some muscle from training. Not like they’re dancing on their own. They harden when I flex, but otherwise, nothing special.

“No need to flex!♥ Just be natural!♥ I’m having fun just touching!♥”

“Really?”

Guess I overdid it.

“Relax, please!♥”

“Got it.”

Maybe she’s aiming for a massage vibe? Her touch isn’t forceful, so it’s not exactly a massage, but still.

She keeps stroking obsessively, chuckling “mufu” under her breath.

Her long black hair sways playfully behind her, her lips glistening with a hint of saliva.

…Did she just slurp?

“Haa…♥ Gorgeous chest…♥”

“…Thanks…?”

She lets out a hot sigh, gazing at my chest with feverish eyes, lovingly tracing it with her fingertips or palm.

…It’s hard to relate, but as a guy, I guess I just find male bodies boring.

She’s enjoying groping my body as the opposite sex, savoring the feel.

Not sure if she’s a muscle fetishist, but she definitely loves my muscles.

With just a thin shirt, her slender fingers tickle me, leaving a restless sensation.

I’d rather see her react to me touching her breasts than have my chest fondled.

Bound like this, I’m craving the feel of her perfectly sized, soft, bowl-shaped, marshmallow-like breasts right in front of me.

I’m in a thin shirt, but so is she.

Beyond the mystical veil of her T-shirt, faintly visible through her bra, lies Mount Olympus, home of the gods.

Covered by her bra, its peaks hidden, yet steadfast, an unshakable presence—

Oh, gods. If only I had the right to behold its raw form. If I had Poseidon’s earth-shaking power. Oh, gods… please, let me join your ranks, even at the lowest seat…

(…Oh.)

Lost in silly thoughts, I felt something odd.

Gazing at her body through her clothes, the smoldering desire inside me seemed to grow, just a bit.

So, desire does intensify when suppressed.

“…♥ …!♥ …♥ …♥”

Meanwhile, Yuu’s still grinning, a bit suspiciously, breathing heavier as she fondles my upper body. She’s brutally honest about her lust. Nice, nice. Her body’s reacting normally to arousal. I’m jealous.

—Then, it happened.

“…”

Yuu’s smile vanished.

Instead of my face, she scanned my entire body, licking it with her eyes.

What…?

“…Ren-chan.”

“Hm?”

She froze, then looked up at me with cautious, almost anxious eyes.

She’s about to say something.

Blinking her long lashes rapidly, her touch turned hesitant as she kept stroking my chest.

“Can I… sniff you…?♥”

“!”

I braced for something wild, but that?

…Given our relationship and everything so far, it’s kind of a “why bother asking” moment.

“Go ahead.”

“Yay!♥”

Why ask now when she usually sniffs me without permission? I held back the quip.

It’s proof she’s still got some rationality, so I decided to avoid interfering and just observe her curiosity about my body. Could be interesting.

“…Snnff♥ Snnff♥ …Haa!♥ Snnff♥ Haa♥ Snnff♥ Haa!♥ Snnff♥ Snnff♥ …Haa~♥”

With my okay, she dove in, sniffing my body without restraint.

My neck, shoulders, armpits (!), chest, sides, back, navel, lower abdomen (!).

It’s embarrassing, and a bit ticklish.

Especially when her nose brushes my skin directly or through my shirt, it stirs weird feelings.

It’s more ticklish than petting a dog or cat. Obviously—she’s the opposite sex.

She’s my mutual love, someone I could have kids with if we wanted.

Her nose grazing my skin naturally stokes my arousal.

It’s practically light foreplay.

“Snnff♥ …Haa♥ Snnff-snnff♥ …Haa!♥ Haa♥ Snnff-snnff♥—”

She sniffs me, kneeling on the bed, straddling my thighs, rising to rub her nose against me, claiming her “sniffing rights.”

“Snnff-snnff♥ Haa♥ Haa♥ Snnff-snnff♥ Haa!♥ Haa!♥”

Her sniffing and breathing grew more intense.

“Snnff-snnff♥ …Haa!♥—”

Her head movements wafted a sweet, fresh shampoo scent, tickling my nose.

We bathed in the same house, used the same shampoo, so it makes sense, but it’s still strange that our hair smells identical.

Our bodies, though, have no artificial scents. We used natural (milk-based) soap.

That soap leaves no lingering fragrance, letting natural body odors shine through, especially with sweat. Perfect for sniffing.

…She didn’t plan that, right?

…Yuu Onodera is thorough.

The Onodera bathroom had a bottle of body wash (probably their usual, from a big brand), but I was banned from using it. Shocked to get second-class treatment as a guest, I was even more surprised when Yuu declared, “I won’t use it either.”

Both of us, nearly scent-free.

Any smell would be pure body odor.

…Obviously (?), I was forbidden from using my deodorant to mask my scent.

Yuu Onodera is thorough.

Her body odor carried faint traces of cooking—oil vapors, grilled fish. A lived-in scent. I love that about her.

That’s noticeable because the milk soap doesn’t linger.

“Hey, Yuu, you love that milk soap, right?”

“Snnff♥—Yup!♥ Love it!♥—Snnff-snnff♥ Haa♥ Snnff-snnff♥—”

Busy as she was, her reply felt like a reflex, but I know she doesn’t love milk soap for its own sake. Its unscented nature suits her purpose.

Come to think of it, since she started staying over, our Hoshimiya bathroom switched to the same soap. She bought and set it up.

No one could miss the hints.

Body odor control. No doubt about it.

And it’s not just scents. Her ingredients fill our fridge, her toothbrush and cup sit in our bathroom. She’s like an invader, spreading her influence over my life, and I’ve let her.

…I thought I’d given up on “normal,” but if I don’t align with some societal norms, this could spiral into a disaster.

I should at least tidy up or fake normalcy when my parents return, as a precaution.

“Snnff-snnff♥—”

“Oh.”

Not satisfied with my upper body, Yuu knelt lower, her nose drifting toward my lower abdomen, then my crotch.

As expected, she’s aiming to sniff there. Her eyes looked bloodshot—not literally, but she was that eager.

—Wait, “as expected”? Why am I ready to have my crotch sniffed?

…Am I already this messed up?

“Ren-chan’s…♥ Cock…♥”

“Hey, hold on—”

Like a gourmet finally facing their main course, cheeks flushed, eyes gleaming, she rubbed her nose against the bulge in my shorts.

“Suuuuuuuuu♥♥♥”

She inhaled deeply.

“…♥♥♥”

And held her breath.

“What!?”

I was stunned.

…You’d be too.

This is peak bizarre.

“What’s this!?”

“…♥♥♥”

Eyes closed, nose still at my crotch, she savored whatever she’d inhaled.

Like a stressed smoker in a smoking area, hoarding the hit.

I’ve seen it at stations or storefronts.

“Y-Yuu…?”

“…♥♥♥”

She’s holding her breath forever.

What’s so fun about this?

I’m mortified.

My readiness for crotch-sniffing was outdone.

What do I do?

What’s the right reaction?

“—♥♥♥”

“Yuu…?”

She lifted her head, eyes wide for a split second.

Then, softly—

“…Nhooo…♥♥♥”

A hot breath escaped her half-open lips.

“Y-Yuu, hey, Yuu.”

“…Aha…♥♥♥”

Her expression was dangerous—very dangerous.

Eyes and mouth half-open.

Completely melted.

Breathing shallowly, staring at some distant horizon.

She’s tripping.

…What? Is she hallucinating from my body odor… my dick smell?

…Does my crotch really smell that potent?

Without sex or heavy exercise, it shouldn’t be that strong. I shouldn’t stink that much, right?

Now I’m worried…

Yuu, after making such a dangerous statement:

“Ren-chan’s scent…♥♥♥ Ohhh!♥♥♥ It’s hitting my womb so hard!♥♥♥♥ So… intense…♥♥♥♥”

“Nn… nngh… uuu~!♥♥♥♥”

She arched her back like a breaching orca, her body convulsing violently—twitch, twitch—on the bed.

“—Haa!♥♥♥ Haa!♥♥♥ Haa!♥♥♥ Haa!♥♥♥ Haa!♥♥♥ Haa!♥♥♥”

Sliding her trembling hips seductively, she collapsed forward, burying her face in my crotch with a thud.

“Yuu!?”

“Ren-chan…♥♥♥ Aha…♥♥♥ Your scent…♥♥♥ I came from it…♥♥♥”

“…”

She climaxed.

From sniffing my penis.

…

“…Yuu. You good now?”

“Y-Yeah…♥♥♥ Just a little…♥♥♥ I might’ve made up for my daily Ren-chan deficiency…♥♥♥”

“I see.”

I was an idiot for worrying, even for a second, that something was wrong with her.

…Well, it’s abnormal, but for her, this is normal.

“So intense…♥♥♥ Cumming from your scent!♥♥♥ It’s like my body’s craving you on a genetic level!♥♥♥”

“Glad to hear it.”

As always, Yuu expresses her love with her unique phrasing.

“…Nf!♥♥♥ Ren-chan!♥♥♥ Ren-chan!♥♥♥ Ren-chan!♥♥♥ Ren-chan!♥♥♥ Ren-chan!♥♥♥ Ren-chan!♥♥♥—”

Her already cute face slackened further, rubbing her cheek against my soft penis through my shorts.

—And not stopping there.

She flicked her tongue out between her lips.

“Lero…♥♥♥”

“Hey, stop that!”

Then she started licking—lick, lick, slurp, slurp—my penis through my shorts.

…It’s a bit late to say, but this is seriously perverted.

“…Nha…♥♥♥ Delicious…♥♥♥”

“No way it’s delicious.”

“Mua…♥♥♥ Lero…♥♥♥ Hamu…♥♥♥”

“Ugh—!? …Hey.”

She licked, then enveloped the bulge of my soft penis, shorts and all, with her open mouth.

Hot breaths swirled inside her mouth, spreading warmth around my lower abdomen. She couldn’t hold back her overflowing, throaty exhales.

It was like a xiaolongbao steaming in a steamer.

Since her mouth covered it, I couldn’t see, but she was licking away with her slick tongue—slurp, slurp.

Naturally, my “xiaolongbao” area was soaked with her saliva. A total mess.

“…Yuu.”

“—Nfufu!♥♥♥ Nfufufu~!♥♥♥”

“Yuu. Hey, Yuu.”

“Nfufufu!♥♥♥ Nfufufufu~!♥♥♥”

“…You’re wild this morning.”

Her brakes—her rationality—are completely shot.

In this near-sealed room, hidden from prying eyes.

With her parents gone, her house is, in a way—

“—This is our love nest now, Ren-chan…♥♥♥”

“Love nest…”

Leaving my drenched crotch as is, she looked up, her feverish, melted face meeting my eyes.

Her gaze, soft and loving, held a dangerously intense light—a mix of love and lust—glimmering eerily.

“Haa…♥♥♥ This…♥♥♥ It’s way more intense than I thought…♥♥♥ I might not be able to hold back…♥♥♥”

“…Hm?”

…Hold back?

She might not hold back?

She’s saying she’s still holding back?

Holding back what?

Was that her idea of restraint?

“…What’s she holding back…?”

“Ren-chaaan…♥♥♥”

With a sloppy, melted grin and a sugary voice, she spoke.

“You’ve gotta work hard today…♥♥♥”

“…Huh?”

I stared, trying to parse her words, as she grinned wider.

“You’ve gotta get your cock working and creampie me today…♥♥♥”

“…What?”

…Sorry.

It’s not that I want to hear her repeat it.

I’m just panicking.

“Maybe I’m an idiot. Yeah, probably my fault, but could you say it clearer? You said today, right?”

I was freaking out.

Her arousal… her blatant perversion, shown without shame or restraint. It’s way beyond what I expected.

At first, she seemed to gauge my limits, but halfway through, she went off the rails.

And if that led to that line…

What does “today” mean?

“…If my impotence doesn’t get fixed today… what happens?”

“…♥♥♥”

“Yuu?”

“…♥♥♥”

She didn’t answer, just gave me a look like, “You know.”

A soft, endlessly slack, sloppy smile.

“…Yuu, say it.”

Cold sweat trickled from my temple.

This is bad.

She’s planning something insane.

She’s about to say something crazy.

“To Ren-chan…♥♥♥—”

My heart pounded like a drum.

She’s dead serious.

I was sure of it.

“I’ll make you hard with medicine…♥♥♥ Get you to creampie me raw…♥♥♥ And we’ll have a shotgun wedding!♥♥♥”

“—Wha.”

Time stopped.

My jaw dropped.

“If this keeps up…♥♥♥ I’ll force you to get me pregnant right away…♥♥♥”

“Wha… what…?”

No mistake.

Her melted smile, sloppy expression, seductive voice.

But deep in her dark, abyssal eyes, a light burned.

“Haa…♥♥♥ Ren-chan…♥♥♥ Hurry…♥♥♥ Get your cock working…♥♥♥ Creampie me…♥♥♥ Or I’ll get pregnant…♥♥♥”

It looked sloppy, but it was strong—too strong—her mad desire teetering on the edge.

“Ren-chan…♥♥♥ Hurry…♥♥♥ If you don’t creampie me soon…♥♥♥ I’ll lose it…♥♥♥”

“Yuu…”

I couldn’t say she’s already lost it.

She’s still sane, somehow.

She could’ve drugged me, stripped my reason away.

That she hasn’t is… better, I guess.

“Ren-chan…♥♥♥ It’s aching…♥♥♥ My womb…♥♥♥ It’s craving you…♥♥♥ It’s begging to get pregnant with your child…♥♥♥”

“No, no pregnancy. Absolutely not.”

“Nooo…♥♥♥ At this rate, I’ll be your wife soon…♥♥♥ Your wife in high school…♥♥♥ I’ll want to bear your child…♥♥♥”

“…Your threats are terrifying.”

If I don’t get hard on my own, she’ll force me to impregnate her.

Horrifying.

“Ren-chan!♥♥♥ Creampie!♥♥♥ Ren-chan…♥♥♥”

“Calm down.”

…Normally, she understands my thoughts.

But her desire’s overridden our “no raw sex for now” promise and her rationality.

…Wait, is she the only one breaking promises?

If I could creampie her, her lust—her pregnancy urge (?!)—might calm down.

So, is this punishment for breaking our “raw sex later” promise because of my impotence?

…When is “later”?

My fault for not nailing down a date…

I underestimated her ability to shatter common sense.

“Time limit!♥♥♥”

“—!?”

A time limit!?

Here comes another crazy twist!

“Until midnight!♥♥♥”

“Midnight—!? What!?”

I figured “today” wouldn’t mean a full 24 hours.

But that’s too short.

“Fifteen hours left!♥♥♥ Creampie me by then!♥♥♥”

“No way…”

Sweat dripped from my jaw.
